Giacomo Tesio 65cdad4317 libc: rewrite putenv and getenv. 
These new implementations

- do several validity check on input parameters
- allow a bit larger variable names (127 bytes, aka sizeof(Proc.genbuf)-1)
- preserve nulls in the content (the original version used to replace
  '\0' with ' '). I can't see why they did, actually.

Should also fix CID 155718
